The test pilot of the Lemming following Sei's death. During her
flight, she encountered Duo, who had borrowed Wing Zero to destroy the
machine. The ensuing battle led the two into space, where the Lemming System
affected Adodera's mind to the point where she opened the cockpit hatch
without wearing a helmet, killing herself.

Madam L / Louisa Lovecraft

An eccentric engineer who created the Lemming, a mobile suit with
performance levels nearing those of a Gundam. The Lemming's main feature,
the Lemming System, affects the mind of anyone within its effect radius,
forcing them into a sort of berserker rage. Madam L apparently cared more
about research than family, since she allowed her daughter Sei to pilot the
dangerous machine, which cost her her life.

Sei

A young woman who had a chance encounter with Duo Maxwell at the
colonies one day. What he didn't realize is that Sei's mother, Madam L, is
an engineer who had designed the deadly and powerful Lemming mobile suit.
During a test flight of the Lemming, Sei is killed by its special Lemming
System.

Most likely the same Wing Gundam used in the
series and that has the same armament capabilities. An alternate theory speculates that it was one of the Gundams sent to
Earth as a part of Operation Meteor, but was not included with OZ's data for
some reason. Its main weapon was a particle sword, a lightweight blade which
could cut through enemy armor on a molecular level.
